2 Introduction Network traffic (text, image, software, audio, video) is increasing continuously both on the Internet and Intranet. A simple, accurate and efficient network traffic monitoring and analysis is required to understand the current usage as well as to plan for future. Many shortcomings exist in currently available monitoring systems. cannot analyze long-term traffic. do not have monitoring capability from multiple network points. capture, analysis and presentation all in one machine. cannot prevent packet drops from the system overload. attempts to overcome these shortcomings using distributed architecture and load balancing technique.
